Each feature from these two sources is mapped to AT LEAST one of the Alexandria Digital Library Feature Types (FTT Version 070302). However, multiple associations can be made. For example, the term bao ta "Sacred relics pagoda" (ID# brkr_520), is listed as ADL type TOWERS, and also as ADL type RELIGIOUS FACILITIES (ID# brkr_1289).

The data dictionary defining the elements used is in "ADL_broker_design.xls"

The first version of this work (circa 2002) was expanded to include Mongolian and Uighur feature types (2003), with the help and cosultation of Dr. James Bosson. The downloadable files contain only the first version, with Chinese, Taiwanese, Japanese and English terms.
